The Digestive System

Written by Phoebe, Lily, and Niko

Today we are going to learn about the digestive system!  First, you break the food into smaller pieces with your teeth.  Next, you swallow the food, and it goes down your esophagus (which is the throat) and into your stomach.  Then, your stomach shakes the food into liquid and sends it through the small intestines while the food is getting thinner and thinner.  

The nutrients from the food passes out of the small intestine to your bloom, and the blood carries the nutrients to every part of your body.  Some of the food goes into your large intestine.  This is the waste that the body doesn't need.  You get rid of the waste when you go to the bathroom.

Have you ever wondered what is the digestive system?

Light and Mirrors in Science

Written by Andrew, Aliza, and Alex (3)

Last week we learned how to reflect light.  We divided into groups of four and turned off the lights.  We used flash lights to shine light onto four different mirrors.  The light bounced from one mirror to the other.  We used clips to hold the mirrors up so that we didn't need to use our hands.

Do you know anything else about light?  Have you ever done this before?

Energy Sources

Written by Alec, Enya, and Niko

We are here to teach you about energy sources.  Did you know that water can be used to create energy because the water turns a wheel that turns a turbine to create energy?  You can also use solar panels that powered by the sun.  Batteries is another energy source.  If gasoline is burned it can fuel a car.

Can you name any other sources?

Solar Cells

Written by Amyyah, Alex (4), and Trinity

In science we also learned about solar cells, which are a solar panel.  If you let the sun hit your solar panel and your whole circuit is connected, your motor will start turning.  It creates solar power and makes the circuit that's connected rotate.  It works with any type of strong light.  Your wires have to be connected for your motor to work.  You need the light to activate with the panel.

Have you ever done this before?

 

Circuits

Written by Alec, Niko, and Enya

In science we learned about circuits.  A circuit is where two wires are touching a power source and generating action.  The name circuit is circle because where you shape the wire it looks like a circle (see pictures below).  A circuit can be powered with different types of sources.  For instant, instead of batteries you can use a solar panel.

Do you have a circuit?
